Since the continuous rotation speed can be up to 150 RPM a CRT type indicator will have a much longer life than a mechanical indicator. The antenna pattern can be seen on the screen and the null direction read out to within 2 degrees.There has been a modification that disconnects the active wire from Diode Input connector on the Front panel and adds a BNC(f) connector to the rear panel, a pot on the rear panel, Red & Black wires coming out the rear panel and a Sense push button on the front panel (maybe to replace a momentary rotary switch?).
On the Front and Rear panel there are a 4 pin Power Input connector (ITT Canon 1S13114E8-4P)
and also a pair of Control Unit connectors (Burndy 14-12P) with 8 small pins and 4 large pins.The name plate says:

C-6183/GR Antenna control - Front & Back
There is a band switch with "sync" and band numbers 1 through 8 (see above table). The antennas all have provision for 8 band positions, but only some are used in any single antenna. The AS-2360 supports band numbers 1 through 5. The bands are changed by means of a 12 position rotary solenoid in the antenna assembly. In position 6 the coil of antenna sense relay (K1) is connected to the "Sense" line pulling the line up to +36 volts (B+) allowing the control unit to synchronize (SYNC) thus learning that the solenoid is on step # 6. I expect that when the antenna control band switch is placed in "SYNC" the solenoid rotates until position 6 where it stops. The solenoid only rotates in one direction 30 degrees per step.The antenna can be rotated continuously at speeds ranging from 15 RPM to 150 RPM (depending on which mount is used) or can be manually turned CW or CCW.
The Front panel has connectors for the Indicator (Bendix PT02E-14-12S) and Pedestal (Bendix PT02E-20-24S) .
The Rear panel has connectors for Power In (ITT Canon 1S13114E8-4S) and Pedestal (ITT Canon MS3114E14-19S).
Why is the rear Pedestal connector different than the Front panel Pedestal connector?The name plate says:

AS-2360 Loop Antenna - Photo
Description from Fair Radio eBay auction:
AS-2360 Loop Antenna .53 Mhz to 10 Mhz, usable to 20.5 Mhz.
Impedance 50 ohms
Null depth 25 db, bearing error less than 2 degrees.
Originally part of TRQ-23 radio receiving set.
The base of the loop contains a loop cathode follower with Varactor diode for tuning, two RF amplifiers, and an output cathode follower using 4/6612 tubes which require 36 v B+, 1.1v filament.
Tuning voltage 0-102 vdc, gain voltage 0-37 vdc, sense relay 24 vdc.
Comes with canvas bag, sense antenna (not pictured), connector for antenna, schematic.
Not tested, used good physical condition. AS IS.
Approx size 6.4 x 26.2 x 61.8 (with sense antenna )

It has 6 separate loop windings that can be connected by relays to operate in band numbers 1 through 5. It also has a Varactor diode to allow resonating the antenna. The R-901/GR and R-902/GR receivers output the diode tuning voltage which is passed through the antenna indicator unit then the control unit and finally to the antenna.

The 30 deg/step rotary solenoid was made by Ledex - p/n 128558-001 date code 7913.
From their records the drive voltage is 28 VDC and a 50 millisecond pulse would be long enough to latch.
Remember that the B+ voltage is 36 (see pin # 7 above).
The 12 position, 4 deck rotary switch was made by Grayhill.The connector on the base of the AS-2360 (inside the lower tube) is a special DB15(m).
It has a coax connector in the center that has a male shield and a female center contact.
It may be a Cannon Combo D but I have not figured out their part numbering system.
Mouser carries a D-Sub Mixed Contact Connector and the 152-FM11W1S housing looks correct.
Page 165 shows these connectors. It's not clear which of 152-FMX1067, 3067, 0003P or 0003S is the correct coax insert.AS-2364 Loop Antenna - Photo

R-901 Receiver
R-1518/URR-71 Receiver
Description
I got this receiver because it has a "DIODE" BNCf connector on the front panel and that's an indicator that it will work with the Rotating antennas that may have started with the TRQ-23. (Also see Radio Direction Finding for earlier CRT based DF equipment)
Portable receiver, battery (12 ea. "D" cells) or external 110/220 VAC power (50 to 400 Hz), or external 24 VDC power;
19.0 to 157.5 MHz, AM, FM, CW.
Uses AS-2887/UR Tape Whip antenna with TNCm connector attached to ANT 1 where "Trim" peaks the response;
CW-1005/UR Field carry bag.
ANT2 is for a 50 Ohm Antenna.
